Thought I would try some aftermarket oil filters from an eBay seller. Nearly died when I got them and compared them to my genuine HD filters. What I found when I opened just floored me. Judge for yourselves:



This is what I found when I first cut this filter open.



Turned the filter element around and noticed it wasn't assembled properly. Glue everywhere.



Sorry for the blur-vision. Spot welds were pretty sloppy.



Notice the spaces where the glue has not been applied? That's going to be one mother of a problem as unfiltered oil makes its way by.



Sealant is missing in big spaces, top and bottom. The brace for the filter element was bent when I opened it (no I didn't do it).



Aftermarket eBay white box filter on the left. Genuine Harley Davidson 63796-77A filter on the right. The difference in quality is night and day.

 

Wow, you are right about the quality difference, night and day.

 

wow your lucky you took the time to take one of them apart and see what was on the inside. How much those set ya back?

 

$68 for a case of 12. I'm sending them back.

 

Yep, that's ugly. Glad you noticed!

 

Thank you for doing y'alls homework!
Lol, that's a "southern" coloquilaism.
But still. This is super pertinent information!
Thank you.

 

I would too. They're hideous!

 

I've always ran K&N, since Mobil doesn't make filters for bikes. I don't run cheap filters on anything I own... it's good insurance

 

 

K&N here as well. When it comes to my bikes or any motor vehicle for that matter, the only place I skimp is maybe finding the best deal on gas with the gas buddy app. But never even worry about that on my bikes. Just making a point. Well, I of course look for the best deal when making modification purchases but point remains. I have bought bulk K&N filters and bulk quality synthetic oil to save a few bucks but never buy junk.
